QuickAddress integration to Navision

Does anyone have a good integration to QAS / QuickAddress Pro (http://www.qas.com) from Navision? We would like the integration to work both from the Customer and the Contact cards, but it’s ok if it only works from one of them.

Have you seen this one? http://www.cosl.co.uk/navision/qas.htm I am not involved in this NSC, just found it googling around

Thanks! I’m just contacting them now!

Please tell me if it’s good (price, code quality etc.) Thanks.
